在数学教学中,为了外显学生的思维过程,挖掘思维的广度和深度,培养学生的抽象概括、求异思维等能力,要鼓励学生在探究算法、操作体验、合作交流、解决问题等方面,大胆说,说观点,说过程,说方法,说算理。通过“说数学”来外显学生思维,促进学生思维。让学生在想、说、算、做中思维更加灵活,思路更加开阔,领悟到学习数学的真正价值,轻松愉快地学好数学。 In mathematics teaching, in order to reveal students ’thinking process, digging the breadth and depth of thinking, cultivating students’ abilities of abstraction, thinking and thinking, and so on, the students should be encouraged to explore algorithm, operation experience, cooperation and exchange and solve problems, Be bold to say, say the point of view, say the process, say the method, say the arithmetic. Through “say math ” to explicit student thinking, to promote student thinking. Let students think, say, count, doing more flexible thinking, more open thinking, realize the true value of learning math, easy to learn math.
